>>1137797Gen 2 is also my favorite.
To put it simply, it is because I like every single one of them, 2 of them (Aqua and Shion) I absolutely love.
While in the other gens there's always 1 or 2 that I either don't like or I am indifferent towards.
Also the interrelations between the members feel more genuine than some of those forced pairings that we get with the later gens (looking at you, PekoMarine).
